2. The soil remediation method of the cyclical photocatalytic soil remediation system of claim 1, wherein: the method comprises the following specific steps:
the method comprises the following steps: original soil is injected into the photocatalytic soil remediation box (21) from the top through the initial soil conveyor (4), and the soil falls on the soil flow guiding and slowing surface (220) of the uppermost photocatalytic soil flow guiding and slowing unit (22);
step two: starting the vibrator (5) to drive the whole photocatalytic soil remediation device (2) to vibrate elastically;
spraying the soil remediation agent to the soil through a soil remediation agent spray nozzle (23);
turning on an ultraviolet lamp (224) to irradiate the soil;
the heating sleeve (2212) is electrified to heat the soil;
starting a motor (2213), and driving all heating sleeves (2212) on the same inclined soil diversion slow flow frame (221) to synchronously rotate through chain transmission to carry out slow flow on the soil so as to reduce the rolling speed of the soil;
the soil falling from the gap of the inclined soil diversion and slow flow frame (221) falls on the inclined soil receiving plate (222) and rolls off;
the soil is sequentially subjected to photocatalytic remediation by each photocatalytic soil diversion and slow flow unit (22) in the photocatalytic soil remediation box (21);
step three: the soil after photocatalytic remediation falls on the first linear conveyor (31), and then is conveyed by the first linear conveyor (31), the spiral conveying elevator (32) and the second linear conveyor (33) in sequence and injected into the photocatalytic soil remediation box (21) again for photocatalytic remediation, so that the circulating photocatalytic remediation of the soil is realized.
